Red-Tagging / Writ of Amparo

Why it matters

The Court declared that red-tagging, vilification, labelling and guilt by association are threats to a person's right to life, liberty or security under Section 1 of the Rule on the Writ of Amparo, which may justify issuing the writ. It reversed the RTC's outright dismissal of an activist's petition and issued the writ, requiring a return and a summary hearing. Whether the privilege of the writ should finally be granted was left to the RTC.

Digest

Facts

Siegfred Deduro is an Iloilo activist, a former Bayan Muna party-list representative, and an officer of Bayan Muna and the Makabayan Coalition. On October 22, 2020, he filed a petition for a writ of amparo in the Iloilo City RTC against Maj. Gen. Eric Vinoya, commander of the Army's 3rd Infantry Division. He alleged that at a June 19, 2020 Provincial Peace and Order Council meeting attended by the media, officers under Vinoya's command presented slides naming him as part of the CPP-NPA hierarchy in Panay, and that the presentation was then publicized. He also cited posters calling him and other activists criminals and terrorists, being followed by unidentified men, red-tagging of his organizations and on Facebook, and the killing of a Bayan Muna coordinator. He sought protection, inspection and production orders. On October 26, 2020, the RTC dismissed the petition outright as baseless and unsupported, without requiring a return. Deduro appealed to the Supreme Court by a petition for review on certiorari under Section 19 of the Rule on the Writ of Amparo. Through the OSG, Vinoya argued that there was no substantial evidence linking him to any threat and that private groups had made the posters.

Issues
  1. 1Whether red-tagging and related acts may constitute threats to life, liberty and security under the Rule on the Writ of Amparo.
  2. 2Whether the RTC erred in dismissing the petition outright, without requiring a return or holding a summary hearing, for failure to show a prima facie case.
Ruling

The Court partly granted the petition. Under Manalo, the right to security of person can exist independently of the right to liberty, so no actual killing, disappearance or deprivation of liberty is needed. The Court reviewed UN reports describing red-tagging as a form of harassment and a likely precursor to abduction or extrajudicial killing, and declared that "red-tagging, vilification, labelling, and guilt by association constitute threats to a person's right to life, liberty, or security, under the second paragraph of Section 1 of the Rules, which may justify the issuance of a writ of amparo." To decide whether to issue the writ, the court reads the petition from the petitioner's side: it asks whether the petition gives the details available to the petitioner and, on its face, shows a violation or threat. Only prima facie allegations are needed at that stage, and the supporting-affidavit requirement allows substantial compliance. Deduro's allegations met that standard. He described the June 19, 2020 presentation by officers under the respondent's command, attached photographs, and cited killings of other persons who had been named. Mere membership in an organization or inclusion in an order of battle is not enough by itself (Ladaga), and whether a threat exists depends on the totality of each petitioner's circumstances. Dismissing the petition without requiring a return denied both parties due process. The Court reversed the RTC order and issued the writ, returnable to the RTC. It ordered Deduro to file a supplemental petition impleading the two private groups behind the posters, required a verified return within 72 hours, and directed the RTC to hold a summary hearing and decide within set periods.
